IGI NIO SICI LIANO BY g ATTORNEY United States Patent 3,189,339 CLOSURE GPERA'I-TOR Iginio Sicilians, 8429 SW. 27th St., Miami, Fla. Filed Dec. 1.2, 1963, Ser. No. 330,153 4 Claims. (Cl. 268-411) This invention relates to operating mechanism for jalousie windows or the like having a plurality of glass panels that are connected by a link bar and whereby a crank arm functions to shift the panels upon their horizontal pivots to multiple positions.

The invention contemplates a crank mechanism that comprises a circular disk having an arm formed thereon that is connected to the operator bar for the several panels of the window and with an actuating bifurcated crank that causes the first disk to rotate and with means to permit the crank arm, after the windows have been shifted and locked in position, to swing downwardly to lie almost completely within the area of a frame in which the windows are mounted and so that the crank arm will not project outwardly to any material extent beyond the reveal of the window opening and to any degree that would offer a hazard to persons walking thereby and that might cause injury to the body of the person and this invention has been designed to avoid any substantial projection beyond, the window opening.

The invention further contemplates a detent that engages any selected notch of the marginal edge of the first disk and with the first disk also being provided with an arcuate. slot having offset extension and a pin carried by the bifurcations of the crank arm that extends through the slot of the first disk and whereby the crank arm may be shifted upwardly to engage the offset end of the slot so that the pin will establish a driving connection with the first disk for moving the first disk upon a cross shaft for operating the window devices and with the crank arm and its bifurcations being subsequently lowered out of the slot extension so that the crank arm may be swung downwardly to a position closely adjacent to the front of the window jamb and with the bifurcations being provided with an elongated slot that engages the cross shaft so as to permit the engagement of the pin in its several positions and whereby the bifurcations may be lifted up or down.

Novel features of construction and operation of the device will be more clearly apparent during the course of the following description, reference being had to the accompanying drawings wherein has been illustrated a preferred form of the device and wherein like characters of reference are employed to denote like parts throughout the several figures.

In the drawings:

FIGURE 5 is a vertical section taken substantially on line 5-5 of FIGURE 4,

FIGURE 6 is a similar view to FIGURE 5, with an exposed plate of the crank arm being shown with parts broken away for purpose of illustration and indicating the movement of the device for the fully closed position of the window panels, and

FIGURE 7 is a section taken substantially on line 7--7 of FIGURE 2.

Referring specifically to the drawings, there has been illustrated a window frame 5, having a plurality of horizontally pivoted panels 6. An operator device indicated "ice as a whole by the numeral 7 is disposed adjacent the lower corner of the window.

A jamb member 8 of the window device is provided with a slot 9 through which the mechanism is installed Within the window and connected to an operator bar 10. The operating mechanism embodies an elongated face plate 11 connected to the jam-b 8 by screws 12. The face plate 11 is also slotted for its major length as indicated at 13. The face plate adjacent its lower portion is provided with a forwardly extending housing 14 that is open at its top and carries a detent ball 15, that is biased upwardly by a spring 16. The face plate 11 is also provided with a pair of spaced apart semi-cylindrical flanges 17 and with the flanges carrying a relatively large cross shaft 18.

A crank arm 19 is formed integral with a pair of spaced apart plates 20 having one side of the plates 20 formed straight as indicated at 21. The plates 20 are provided with elongated slots 22 that override the shaft 18 and whereby to permit movement of the plates 20 upwardly and downwardly with respect to the shaft 18. The plates 20 also carry a pin 23 constituting the actuating means for a window control device to be described.

Rotatably disposed upon the shaft 18 and between the plates 20, is an operating disk 24 having an arm extension 25 that is pivotally connected at 26 to the bar 10. The disk 24 is provided with a concentric slot 28, having offset end portion 29 and the slot 28 and offset portion 29 receive the pin 23 carried by the plate 20. A lower marginal edge of the disk 24 is notched at 30 to engage the ball detent 15 and the several notches 30 have been so spaced as to actuate the window to and from a fully closed position and intermediate positions.

In the use of the device, the actuating mechanism is assembled and connected to the jamb 8 by the screw 12. When the window is to be opened, the crank arm 19 is swung upwardly and shifted upwardly to cause the pin 23 to enter the offset slot 29. In this position, the crank arm 9 is projecting outwardly from the window in substantially horizontal position and, the crank arm is then swung downwardly, rotating the disk 24 to shift the bar 10 upwardly to any open position, determined by the engagement of the ball detent 15 into any one of the notches 30. When the window has been fully opened, the crank arm 19 and its plates 20 are pivoted downwardly through the medium of the slot 22, moving the pin 23 out of the oifset 29, permitting the plates 20 and the crank arm to be swung downwardly to the position indicated in FIGURE 5. When the window is to be closed, the crank arm 19 is swung upwardly, causing the pin 23 to traverse the arcuate slot 28 until it reaches the offset 29 so that the plates 20 and the crank arm 19 may be moved upwardly to engage the offset 2?, permitting the crank 19 to then shift the disk 24 in a clockwise direction. When the window is fully closed, the plates '20, carrying the pin 23 are shifted downwardly to move the pin 23 out of the offset 29, permitting the pin 23 to again traverse the slot 28 and so that the crank may drop downwardly to lie closely adjacent to the jamb. The endmost notches 30 determine the fully closed and fully opening position of the window and with the ball detent substantially locking the window against movement in either direction. The intermediate notches 30 determine the partial opening or closing of the window. It is contemplated that the mechanism shall be formed of light weight metal, such as aluminum, having a high resistance to corrosion.

It will be apparent from the foregoing that a very novel type of window operating mechanism has been provided. The structure is simple, is strong, durable and provides a device for shifting the panels of a jalousie window to and from an open position. In each position of the window, the crank arm 19 and its associated plates 2% carrying the pin 23 may be shifted downwardly so that the crank arm 19 will not project outwardly from the window but is at all times, regardless of the position of the window, able to move the crank arm 19 out of any extending position that would be deterimental to persons who might be injured by an extending crank. The device is a very distinct improvement over prior art devices for shifting jalousie panels.

It is to be understood that the invention is not limited to the precise construction shown, but that changes are contemplated as readily fall within the spirit of the invention as shall be determined by the scope of the subjoined claims.
